This Los Angeles to Sydney routing is pricing at 55,000 United MileagePlus miles in economy, compared to the roughly 60,000 miles you'd typically see for this long-haul transpacific flight. The savings of around 5,000 miles per ticket adds up quickly for families booking multiple seats.

Availability appears wide open for travel on April 21, 2026, which falls during a pleasant autumn season in Australia. The low taxes of just $37 make this an efficient use of miles without the sting of carrier surcharges that often accompany international awards.

At 14-plus hours of flight time, economy to Australia is a long haul for anyone. Consider seats toward the front of economy for slightly faster deplaning, and check United's seat map early since award tickets often get last pick on seat selection.
